Total SF6-emission contribution only 0,28 %SF6-emission from electric power equipment: 0,05 %(„closed and sealed pressure systems“); in Germany: 0,03 % !
Other SF6-emission sources were: magnesium and aluminium industry, footwear, tyres,window noise insulation, military applications, semiconductor industry, medical devices (mainly „open applications“)

In 2002 in the EU-15 the SF6-emission of electrical power equipment was 0,05 % of all greenhouse gases → Slide 4
Volunteer actions of manufacturers and users of electrical high and medium voltage equipment in Europe realized a reduction of 40% SF6-emission in the last 10 years
Additional reduction of SF6-emisson possible – improve tightness, gas-recycling; complete & Europe-wide realization of this activities in the future
Environmental life cycle assessments show a relief of the CO2- balance by using SF6-technology

Low leakage rates during lifetime of equipment
Comply with the EU-F-Gas regulation and additional SF6-voluntary commitment (in selected countries)
Training & certification of staff handling/recovering SF6
Use of state-of-the-art equipment for SF6 handling (factory, on-site service)
Continuous improvement of products (more compact, less emission)
What can users of SF6-electric power equipment expect from the manufactures?

Conclusion
SF6 → excellent insulation and arc quenching; no equivalent at the moment
SF6-technolgy → compact equipment with low material usage, high operational safety, minimized fire load, high availability
Positive ecological balance → lower energy losses compared to conventional AIS solutions (therefore CO2-reduction)
Potent greenhouse gas → low leakage rates and handling losses necessary, reuse-concept to be considered during maintenance and end-of-life
Further European & world-wide realization of emission reduction necessary
